ExamPilot is a full-stack exam scheduling and management web application designed to make planning and organizing exams easier. I developed the application with a React frontend and Spring Boot backend, using MongoDB for data storage. The platform includes secure authentication, exam folder management, timetable creation, PDF export, responsive design, and real-time updates.

Offline-First Healthcare PWA (Clinic Management)
Developed a multi-tenant Progressive Web App (PWA) handling 100+ daily patients.
Key Features:
